Abstract

<P>PROBLEM TO BE SOLVED: To provide a bird damage-preventing cap for effectively and surely protecting fruits scattering in a field from birds with minimum materials and labor. <P>SOLUTION: The bird damage-preventing device is constituted by installing legs (2) on the lower part of a cap (1) to ensure to set the bird damage- preventing device just above the fruit and bring the cap to the inserted in a narrow space where vines and leaves are growing. Passages (4) are made below the cap (1) so as the vines, branches and leaves can grow inside and outside of the cap (1). The cap (1) has a network or hole structure to pass the sun light and permeate air, is made of a material protecting the cap from strong beaks of crows and tightly fixed by fixing the legs by using falling-off preventing pins (3) to prevent the cap from blowing away. Light reflecting mirrors (5) are installed on the surface and the top of the cap to bring the birds to difficultly approach the cap so as a field is not damaged by the birds. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention replaces the conventional method of installing and protecting a large net, and is a technique for producing a fruit bird damage prevention apparatus that is compact, easy to attach and detach, and has a reliable effect. Is.

[0002]

2. Description of the Related Art A method of covering the whole field with a net is sure,
Since there is a difficulty that requires a great deal of material and installation labor, as an alternative method, Sakayamako, roaring noise, eyeball balloons fluttering in the wind, electromagnetic wave application, etc. are used, but these gradually get used to birds. There was a problem with certainty, such as bird damage.

[0003]

The conventional method of constructing a net requires a great deal of material and labor, and after installation, there are restrictions on the entrance and exit of the net and the work inside depending on the net. It is difficult to do so, and it is inefficient to protect the sparsely scattered fruits in a wide field. As a measure against this, even in a wide field, it is efficient, reliable, compact, and easy to put on and take off.
Invent a bird damage prevention device that does not hinder work after installation.

[0004] Fruits such as watermelons are present in the vertical and horizontal clusters of vines or branches and leaves among the fruits. In a bird damage prevention device in the form of a simple cap, these interfere with each other, and It cannot be placed in position, and in that state it cannot be firmly fixed to the ground. As a countermeasure against this, we invent a bird damage prevention device in which vines and branches are densely arranged vertically and horizontally and which can be installed anywhere.

Fruits such as watermelon are a source of nutrition
To invent a bird damage prevention device which has vines and branches and which does not damage them or hinder their growth.

[0006] Ventilation and sunlight are sufficiently taken in so as not to hinder the growth of fruits, and from strong beaks such as crows,
Invent a bird damage prevention device that is protected.

The bird damage prevention device invents a bird damage prevention device which is not blown off by a strong bird such as a crow or blown by the wind.

[0008] A bird damage preventive apparatus is invented which makes it difficult for birds to approach, because the effect is halved if the field is damaged due to the approach of birds as well as fruits.

[0009]

[Means for Solving the Problems] A compact bird damage prevention device intended for directly covering the sparsely scattered fruits in a field without using a large net. The cap portion (1) is provided.

A leg (2) having a shape that does not interfere with the growth of vines and branches and leaves is provided at the bottom of the cap, and the tip of the leg is
It is shaped so that it can be installed directly above the target fruit by inserting it between narrow spaces such as vines and branches that are crowded vertically and horizontally.

The lower part (4) of the cap has a shape that maintains a constant gap with the ground, and is provided as wide as possible as an entrance / exit for the vines extending to the fruit and the branches and leaves inside and outside the cap.

The cap portion (1) has a mesh, in order to have sunlight and air permeability so as not to interfere with the natural growth of fruits,
Alternatively, it is a material and structure having a mesh size and strength, which has a hole structure and is protected from a strong beak such as a crow.

Even if a large bird such as a crow rides on it, the legs are integrated or separate so that the cap is not blown off even if the wind blows. It is something that is fixed.

When a light reflector (5) is placed on the surface of the cap and on the top of the cap and a bird tries to approach the cap,
In accordance with the movement of the bird, a cap sphere and a reflecting mirror placed on the top emit dynamic, glittering light to make it difficult for the bird to approach.

[0015]

DETAILED DESCRIPTION OF THE INVENTION The cap (1) and leg (2) are
Made of metal or resin, integrally molded, or using this as a skeleton, add a net, or an alternative to this, and make it in a combined form to have a certain strength to withstand the beak and weight of a crow, etc. I have.

A leg (2) is provided on the lower part of the cap, and the tip of the leg is easy to insert and install in a narrow space where vines and branches are randomly crowded.
It is shaped.

The lower part of the cap is provided with a shape of a passage opening (4) to maintain a certain gap between the cap and the ground, and to freely feed the fruits such as vines and branches into and out of the cap. As a way, it is designed so that it will not hinder growth.

The cap portion (1) is of a structure having a mesh or hole shape of a size that is natural, breathable, can sufficiently receive sunlight, and can protect fruits from beaks such as crows.

As a method of fixing the main body, the legs are integrally or separately provided, and a pin (3) having a slip-out preventing member is used to prevent the pin from being easily removed by a bird or the like.

Reflectors placed on the surface of the spherical cap and polyhedral reflectors (5) on the apex are arranged. When a bird approaches the cap, the reflector placed on the cap spherical body moves in accordance with the movement of the bird. , It emits a dynamic, glittering light, makes it difficult for birds to approach, and makes sure that the fields as well as the fruits are not destroyed.

[0021]

[Effects of the Invention] For fruits scattered in a field,
Efficiently, easily and with a minimum of materials, you can reliably protect fruits from birds without installing a large net.

The disadvantage of the conventional nets is that they no longer have to go in and out of the nets to work, and the restrictions on the work due to the nets are released and fruit management becomes easier.

It is easy to put on and take off, can be used repeatedly, and is economical.
